21、anufacturing schedule, no change shall be made without the written approval of the purchaser. 6.4 The product shall be supplied in the heat treatment condition specified in the material standard. If otherwise agreed or if there is more than one heat treatment condition in the material standard, the
22、condition of supply shall be specified on the order, drawing or manufacturing schedul e. 6.5 that temperature shall be mandatory. If a specific heat treatment temperature (value and to erance) is stated, If a heat treatment temperature raiige is stated, a temperature within that range, reduced by th
23、e furnace tolerances, shall be selected to give the required properties.
